Structurally, it features a vigorous rhizome and is widely used as an ornamental plant in gardens due to its resilience and spectacular appearance.
- Agapanthus orientalis — A species of perennial plants in the genus Agapanthus, native to the eastern provinces of South Africa, often classified as a subspecies of Agapanthus praecox. This structurally robust plant is characterized by broad, evergreen, elegantly arching leaves and massive globose inflorescences capable of supporting up to one hundred blue or white tubular flowers, forming the genetic basis for most modern large horticultural cultivars.
- Agastache — A genus of aromatic herbaceous perennial plants belonging to the Lamiaceae family, mostly native to North America and partially to East Asia, popularly known as giant hyssop or hummingbird mint; characterized by toothed leaves, often with a pronounced scent of mint, anise, or lemon, and dense spike-like inflorescences composed of numerous tubular bilabiate flowers. Structurally, the plants feature rigid quadrangular stems and are widely used as ornamental, medicinal, and honey-bearing plants in gardens.
- Agave americana — A famous species of succulent and xerophytic plant within the genus Agave, native to Mexico and the United States, but widely naturalized globally, including the Mediterranean basin. Commonly known as the American aloe or century plant due to the misconception that it blooms only once every hundred years, it is distinguished by its impressive size, grayish-green leaves with spiny margins, and a spectacular inflorescence that can reach up to eight meters in height.
- Agave geminiflora — A unique species of succulent plant within the genus Agave, native to the state of Nayarit, Mexico. This plant is structurally characterized by an extremely dense and symmetrical rosette composed of hundreds of narrow, linear, flexible, and rounded leaves, lacking marginal teeth but often featuring decorative white filaments peeling from the edges. Its specific epithet refers to its spectacular flowering spike, where the flowers appear arranged in twin pairs along the stalk.
- Ageratum houstonianum — A species of annual herbaceous plant in the genus Ageratum, native to Central America and Mexico, widely cultivated globally as an ornamental border plant. It is noted for its compact mounds and dense capituliform inflorescences, with the flower heads resembling blue, lavender, pink, or white floss-like tufts, highly valued in urban landscape design.
- Creeping bentgrass — A species of perennial herbaceous plants within the genus Agrostis, family Poaceae, characterized by producing long, creeping stolons that form an extremely dense, fine, and elastic green carpet. Due to its remarkable rapid regeneration capacity and tolerance to very low mowing, it is widely utilized worldwide for establishing golf course greens, luxury sports fields, and high-quality ornamental turfgrass.
- Allamanda violacea — The scientific name of a tropical climbing plant species in the family Apocynaceae, synonymous with Allamanda blanchetii, prized for its distinctive violet-pink or purple funnel-shaped flowers. Native to Brazil, this vigorous vine is distinguished by its slightly hairy (pubescent) stems and leaves, and is heavily used to decorate fences, pergolas, and arches in warm climate zones.
- Alocasia macrorrhiza — The scientific name of the giant taro or giant elephant ear, a massive herbaceous plant in the Araceae family, native to the tropical regions of Southeast Asia and Australia; it is structurally characterized by gigantic erect leaves that can reach lengths of over one meter and a thick pseudo-stem formed by overlapping petioles.
- Alpinarium — A decorative botanical garden of variable sizes, a special sector arranged within a park, or a structural landscape design crafted from stone blocks, rocks, and soil, designed for cultivating and presenting collections of dwarf alpine, subalpine, and mountain plants under conditions mimicking their natural habitats.
- Alternanthera bettzickiana — A species of perennial herbaceous plant in the family Amaranthaceae, native to South America; it is widely used in global ornamental horticulture due to its dense foliage, variegated or blotched in spectacular shades of red, purple, yellow, and cream, making it ideal for low borders and landscape mosaics.
- Amaranthus salicifolius — The scientific name or botanical synonym for Amaranthus tricolor var. salicifolius (commonly known as willow-leaved amaranth), an annual ornamental variety highly valued for its long, narrow, drooping foliage that resembles willow leaves. It exhibits a striking color transition during its growth cycle.
- Amelanchier canadensis — A species of shrub or small tree in the genus Amelanchier, Rosaceae family, native to eastern North America and Canada, popularly known as the 'Canadian serviceberry' or 'shadblow serviceberry'. The plant structurally grows in wet areas, swamps, or floodplains and is characterized by dense, multi-stemmed clumps, white flowers grouped in erect racemes, and edible black-purple globose fruits highly valued by wildlife.
- Tall kangaroo paw — The most robust and adaptable species of the Anigozanthos genus, native to the damp and forested regions of Southwestern Australia. This structural perennial plant is distinguished by imposing flower stalks that can reach two meters in height, evergreen sword-like leaves, and velvety yellow-green inflorescences, being heavily used in hybridization due to its high resistance to fungal diseases and temperature fluctuations.
- Shrub — A perennial plant with a woody stem, smaller in size than a tree, which branches out directly from the ground level or its immediate vicinity without developing a single, clearly defined main trunk. In forestry and ecology, shrubs make up the undersets of forests, playing an essential ecological role in soil protection and providing wildlife habitat.
- Aristolochia durior — A synonymous or historical scientific name for a vigorous climbing plant species, known in modern taxonomy primarily as Aristolochia macrophylla (pipevine). Native to eastern North America, the plant is distinguished by its giant, heart-shaped leaves that create a dense canopy of greenery, and its unique pipe-shaped curved flowers, widely used in landscaping to cover pergolas and walls.
- Armeria maritima — Scientific name for a popular species of perennial herbaceous plant in the Plumbaginaceae family, commonly known as thrift, sea thrift, or sea pink. This highly salinity-tolerant structural plant is native to maritime coasts across the Northern Hemisphere, forming compact grass-like tufts with erect stems bearing pink, white, or purple globose inflorescences, widely used as a border and rock garden ornamental.
- Arundinaria hindsii — The scientific name of an erect bamboo species native to East Asia (currently known taxonomically as Pleioblastus hindsii). This perennial plant from the Poaceae family is structurally characterized by slender, rigid, dark green culms that grow densely and compactly, frequently used in landscape architecture for creating resilient natural screens and ornamental hedges.
- Aster x frikartii — The scientific name of a famous perennial garden hybrid aster, obtained by crossing Aster amellus and Aster thomsonii by the Swiss nurseryman Frikart in 1918; it is globally renowned in landscape design for its exceptionally long blooming period (from July to October) and large, bright lavender-blue flower heads featuring a prominent central yellow disc.
